IEC 61666 establishes general principles for the designation of terminals of objects within a system. These principles are of general nature, hence applicable to all technical areas (mechanical, electrical, construction, process engineering, etc.). They can be used for systems based on different technologies as well as systems combining multiple technologies. This first amendment modifies several figures in clause 4.
